A$AP Rocky joined Danny Brown at Wembley Stadium to do a rendition of "1 Train".

While Em brought out Dre during his performance, Danny made sure to supply a surprise of his own, bringing out A$AP Rocky to do "1 Train". The reunion comes only a short while after Brown pre-emptively called out A$AP Mob for taking his verse off "Hella Hoes", later determined to be a label decision.
